Coil Gun

Home/Coil Gun

Project Description

The Coil Gun has a modular design. Each 3D printed module houses of a capacitor bank, an accelerator coil, an optical trigger and a charging circuit. The modules can be stacked. The modules could probably be improved by adding circuitry for sensing the speed of the incoming projectile, and then use this as a factor when calculating the timing of the next pulse.

You can find more info on the charging circuit and modules on GitHub, but I will not provide a full schematic for this device. It looks (and probably also performs) like a toy, but the energy levels involved are lethal. Each module will dump approximately 670A into the drive coil in 8ms. If you accidentally touch a HV terminal, you won’t just get burnt – blood vessels in your body will most likely explode. A “capacitor mishap” will guarantee a visit to the emergency room – dead or alive.

Kanonstøperiet – del 4 (The shape of things to come)

By |January 25th, 2012|Categories: 3D Printing, CAD, Coil Gun, Electronics|

Jeg er igjen svanger med en liten statusrapport.  3D-printern har gått i ett de siste dagene, og det luktet i perioder så kraftig at hele kostebinderiet måtte flyttes inn i vaskerommet, som har mekanisk avtrekk. [...]

Kanonstøperiet – del 3 (Instrumentmakeren)

Hvis man skal unngå alt for mange parameterskudd ut i mørket når man bygger sin elektriske kanon, så er man avhengig av å kunne måle effekten av de endringer man gjør underveis. Jeg har derfor [...]

Kanonstøperiet – del 2 (XP+1, level up !)

By |November 27th, 2011|Categories: 3D Printing, Coil Gun, Electronics|

Den siste uka har gått med til å dra frem mattebøker fra hylla, legge dem på fanget, lese litt og så gråte en skvett over hvor inn i helsike mye en ikke kan lenger. Samtidig [...]
